Cables and Connections

MN/CRS300.IOM

2.The Traffic CDM-700 must have the same interface cards in each slot as any of the other Traffic CDM-700s have, or a blank panel installed.

3.OC3 Optical TMI is not currently available.

4.As of April 2007:

CRS-336 TMI card replaces the CRS-335.

CRS-306 RMI card replaces the CRS-305.

4.7.3Control Cable Connections – CRS-300 to Modems

The Control Cable CA/WR12361-1 provides the serial communication path between the Switch and the modems and controls the modem’s external Tx IF-mute control line, and is therefore always required.

Refer to Figure 4-22and Figure 4-23to connect and secure the CA/WR12361-1 cables between the CRS-300 and each CDM-700 as follows:

HD-15F connector labeled “J1” on the RMI or TMI(s), to

DB-15M connector labeled “P1 Alarms” on the CDM-700.

4.7.4Serial Traffic Data Connections – CRS-300 to Modems

If G.703 is the traffic data type, refer to Figure 4-22,Figure 4-23,Figure 4-25, or Figure 4-27to connect and secure the Traffic Data Cables CA/RF12278-1 and CA/RF12279-1 the CRS-

300 and each CDM-700 as follows:

First, connect and secure the CA/RF12279-1 cable between the Redundant CDM-700 and the CRS-300:

DB-15M connector labeled “P1” on the RMI, to

BNC connectors (<4X> per installed CDI-10 card) on the Redundant CDM-700 (depending on the modem configuration, either <4X> or<8X> BNC connectors are used).

Next, connect and secure the CA/RF12278-1 cables between the CRS-300 and the Traffic CDM-700(s):

DB-9M connector labeled “P1” on the TMI(s), to

BNC connectors (4X per installed CDI-10 card) on each Traffic CDM-700 (depending on the modem configuration, either <4X> or <8X> BNC connectors are used).

If HSSI is the traffic data type, refer to Figure 4-23and Figure 4-26to connect and secure the HSSI Data Cable CA/WR9189-6 between the CRS-300 and each CDM-700 as follows:

HSSI (HD-50F) connector labeled “J2” on the RMI, or “J3” on the TMI(s), to

HSSI (HD-50F) connector labeled “HSSI” on each CDM-700.

If OC3 copper is the traffic data type, refer to Figure 4-24to connect and secure the pair of BNC PL/0813-8 cables between the CRS-300 and each CDM-700 as follows:

BNC connectors labeled "J4 Tx" on the RMI, or "J3 Tx"on the TMI(s), to BNC connectors labeled "Tx" on the CDM-700's CDI-50 interface card, and

BNC connectors labeled "J3 Rx" on the RMI, or "J5 Rx"on the TMI(s), to BNC connectors labeled "Rx" on the CDM-700's CDI-50 interface card.
